Where can I buy cheap and genuine books?

Confucius Old Book Network or China Book Network.

The unique selling point of Confucius Old Books Network is that there are ancient books, rare books, dated books, and even some unpopular books that can't be sold can be found here. But the price is high or low, and the postage is more expensive than China Book Network.

It is worthwhile to find some books to supplement key knowledge areas. Since the media is to find differentiated knowledge points, it can explode.

China Book Network is a website, which mainly focuses on books of various publishing houses, some of which are unpopular, removed from bookstores or relatively unpopular, and there are also many good books. Discounts are really difficult, and they are all sold by the box, which is guaranteed. Of course, the shortcomings of this website are also very obvious, because it is a tail book, so this book may have some minor flaws in appearance. There are many kinds of books, but the activities with big discounts are mainly classic books and few bestsellers.
